Session tickets, defined in +RFC5077 provide an enhanced session resumption capability where the server +implementation is not required to maintain per session state. It only applies +to TLS and there is no SSLv3 implementation. + +The callback is available when the OpenSSL library was built without +I<OPENSSL_NO_TLSEXT> being defined. + +The callback function I<cb> will be called for every client instigated TLS +session when session ticket extension is presented in the TLS hello +message. It is the responsibility of this function to create or retrieve the +cryptographic parameters and to maintain their state. + +The OpenSSL library uses your callback function to help implement a common TLS +ticket construction state according to RFC5077 Section 4 such that per session +state is unnecessary and a small set of cryptographic variables needs to be +maintained by the callback function implementation. + +In order to reuse a session, a TLS client must send the a session ticket +extension to the server. The client can only send exactly one session ticket. +The server, through the callback function, either agrees to reuse the session +ticket information or it starts a full TLS handshake to create a new session +ticket. + +Before the callback function is started I<ctx> and I<hctx> have been +initialised with EVP_CIPHER_CTX_init and HMAC_CTX_init respectively. + +For new sessions tickets, when the client doesn't present a session ticket, or +an attempted retreival of the ticket failed, or a renew option was indicated, +the callback function will be called with I<enc> equal to 1. The OpenSSL +library expects that the function will set an arbitary I<name>, initialize +I<iv>, and set the cipher context I<ctx> and the hash context I<hctx>. + +The I<name> is 16 characters long and is used as a key identifier. + +The I<iv> length is the length of the IV of the corresponding cipher. The +maximum IV length is L<EVP_MAX_IV_LENGTH> bytes defined in B<evp.h>. + +The initialization vector I<iv> should be a random value. The cipher context +I<ctx> should use the initialisation vector I<iv>. The cipher context can be +set using L<EVP_EncryptInit_ex>. The hmac context can be set using L<HMAC_Init_ex>. + +When the client presents a session ticket, the callback function with be called +with I<enc> set to 0 indicating that the I<cb> function should retreive a set +of parameters. In this case I<name> and I<iv> have already been parsed out of +the session ticket. The OpenSSL library expects that the I<name> will be used +to retrieve a cryptographic parameters and that the cryptographic context +I<ctx> will be set with the retreived parameters and the initialization vector +I<iv>. using a function like L<EVP_DecryptInit_ex>. The I<hctx> needs to be set +using L<HMAC_Init_ex>. + +If the I<name> is still valid but a renewal of the ticket is required the +callback function should return 2. The library will call the callback again +with an arguement of enc equal to 1 to set the new ticket. + +The return value of the I<cb> function is used by OpenSSL to determine what +further processing will occur. The following return values have meaning: + +=over 4 + +=item Z<>2 + +This indicates that the I<ctx> and I<hctx> have been set and the session can +continue on those parameters. Additionally it indicates that the session +ticket is in a renewal period and should be replaced.

It makes up for this by storing client certificate +an all other negotiated state information encrypted within the ticket. In a +resumed session the applications will have all this state information available +exactly as if a full negiotation had occured. + +If an attacker can obtain the key used to encrypt a session ticket, they can +obtain the master secret for any ticket using that key and decrypt any traffic +using that session: even if the ciphersuite supports forward secrecy. As +a result applications may wish to use multiple keys and avoid using long term +keys stored in files. + +Applications can use longer keys to maintain a consistent level of security. +For example if a ciphersuite uses 256 bit ciphers but only a 128 bit ticket key +the overall security is only 128 bits because breaking the ticket key will +enable an attacker to obtain the session keys. + +=head1 EXAMPLES + +Reference Implemention: + SSL_CTX_set_tlsext_ticket_key_cb(SSL,ssl_tlsext_ticket_key_cb); + .... + + static int ssl_tlsext_ticket_key_cb(SSL *s, unsigned char key_name[16], unsigned char *iv, EVP_CIPHER_CTX *ctx, HMAC_CTX *hctx, int enc) + { + if (enc) { /* create new session */ + if (RAND_bytes(iv, EVP_MAX_IV_LENGTH) ) { + return -1; /* insufficient random */ + } + + key = currentkey(); /* something that you need to implement */ + if ( !key ) { + /* current key doesn't exist or isn't valid */ + key = createkey(); /* something that you need to implement. + * createkey needs to initialise, a name, + * an aes_key, a hmac_key and optionally + * an expire time. */ + if ( !key ) { /* key couldn't be created */ + return 0; + } + } + memcpy(key_name, key->name, 16); + + EVP_EncryptInit_ex(&ctx, EVP_aes_128_cbc(), NULL, key->aes_key, iv); + HMAC_Init_ex(&hctx, key->hmac_key, 16, EVP_sha256(), NULL); + + return 1; + + } else { /* retrieve session */ + key = findkey(name); + + if (!key || key->expire < now() ) { + return 0; + } + + HMAC_Init_ex(&hctx, key->hmac_key, 16, EVP_sha256(), NULL); + EVP_DecryptInit_ex(&ctx, EVP_aes_128_cbc(), NULL, key->aes_key, iv ); + + if (key->expire < ( now() - RENEW_TIME ) ) { + /* return 2 - this session will get a new ticket even though the current is still valid */ + return 2; + } + return 1; + + } + } + + + +=head1 RETURN VALUES + +returns 0 to indicate the callback function was set. + +=head1 SEE ALSO + +L<ssl(3)|ssl(3)>, L<SSL_set_session(3)|SSL_set_session(3)>, +L<SSL_session_reused(3)|SSL_session_reused(3)>, +L<SSL_CTX_add_session(3)|SSL_CTX_add_session(3)>, +L<SSL_CTX_sess_number(3)|SSL_CTX_sess_number(3)>, +L<SSL_CTX_sess_set_get_cb(3)|SSL_CTX_sess_set_get_cb(3)>, +L<SSL_CTX_set_session_id_context(3)|SSL_CTX_set_session_id_context(3)>, + +=head1 HISTORY + +This function was introduced in OpenSSL 0.9.8h + +=cut diff --git a/doc/ssl/SSL_CTX_set_tmp_dh_callback.pod b/doc/ssl/SSL_CTX_set_tmp_dh_callback.pod index 29d1f8a..b34c68a 100644 --- a/doc/ssl/SSL_CTX_set_tmp_dh_callback.pod +++ b/doc/ssl/SSL_CTX_set_tmp_dh_callback.pod @@ -12,12 +12,10 @@ SSL_CTX_set_tmp_dh_callback, SSL_CTX_set_tmp_dh, SSL_set_tmp_dh_callback, SSL_se DH *(*tmp_dh_callback)(SSL *ssl, int is_export, int keylength)); long SSL_CTX_set_tmp_dh(SSL_CTX *ctx, DH *dh); - void SSL_set_tmp_dh_callback(SSL_CTX *ctx, + void SSL_set_tmp_dh_callback(SSL *ctx, DH *(*tmp_dh_callback)(SSL *ssl, int is_export, int keylength)); long SSL_set_tmp_dh(SSL *ssl, DH *dh) - DH *(*tmp_dh_callback)(SSL *ssl, int is_export, int keylength)); - =head1 DESCRIPTION SSL_CTX_set_tmp_dh_callback() sets the callback function for B<ctx> to be @@ -81,7 +79,7 @@ instead (see L<dhparam(1)|dhparam(1)>), but in this case SSL_OP_SINGLE_DH_USE is mandatory.
